What did you do airgun related today.

I shot my HW95 .20 cal. I love this gun. I have PCPs but there is something about a springer that's so relaxing, Zen like. First shot of the day from 25 yards with peep sight. Front arm wrapped in the sling resting on the back of a chair butt stock in my shoulder.

Air gun related yes , looked at the weather forecast and it looks like the next few days the remnants of storm Helen will pass right over supposed to rain and 16 to18 mile wind gust at times , as long as i stay dry i will try to shoot @ 20 yards . when you get lemons you make lemonade .
 
So, how to grade air guns design and OEM selection of O-rings. You can't live with air guns and not have o-rings. So, 1) what is the best material for air gun O-rings? @) Do different areas/applications require different materials and/or durometers. 3) Do manufacturers just throw whatever size and type of o-ring than can get in terms of economy of scale? 4) Can I select a better O-ring, including size, material and durometer than OEM? I would suggest that an airgun that uses fewer O-rings might be a better design? So in the sales pitch of an airgun why not pitch O-ring replacement advantages.

For instance, an air gun leaks. Instead of having the owner agonize of where the leak is, why not just design the gun to easily change out the O-rings without having to have a physics degree from MIT?

I use Buna-N (Nitrile) O-rings almost 100% on my rebuilds. Most are 70 durometer with a few specific ones needing 90+. Some older CO2 airguns require nylon O-rings in specific area. The higher the durometer, the harder it is to install and not damage it. Also in manufacturing process, the more complex the design is to eliminate sealing areas, the higher the cost to make it. There has been a lot of progress in minimizing sealing area due to process automation. I spent more than 20 years in manufacturing process development.
 
@Genob , for instance. I got a "massive" O-ring kit from Amazon, Buna-N and 70 D. One of my AA S200 air tubes was leaking. I replaced the major o-ring with one from the "kit." Pumped the gun up to 2700psi and let it sit, it held. I simply dropped the old o-ring into the slot of what appeared to be the right size and away we went, easy peasy.

Yes same here, I have several amazon and Grainger master kits. Amazon black O-rings are 70 duro and the reds are in the 50's.

Retuned the Impact M3 .22 compact I am to sell tomorrow, from 790fps with the 21.9gr AEA pellets to 935fps.

Packed and shipped the Notos bottle conversion as well as the .177 barrel kit, mags and probes.

Also started working on my coworkers dreamline as it is leaking air through the reg, and the reg gauge is climbing faster than the air gauge.

Also took my other buddy's coworkers dreamline as I will need a gun for iguana removal this week.

Started to work on my nephews Beeman 1362, this is his 1st pcp airgun he bought with his money. It's very loud for backyard use. So I'm trying to quite it down and also shorten the LOP for him. Discarded the plastic and moderator, made an air striper tensioner in place so he can use any moderator he wants. Making a new rubber butt pad to reduce LOP 1/2 inch, also shortened the trigger link rod 3/16" to shorten free travel. Adjusted the sear to 0.030" as it had too much creep. Well, it went from a lousy trigger to an acceptable one ( 5.5 lbs. to just over 2 lbs.) OAL is now 28" without moderator.

More pellet testing. #1 is still RWS R10 8.2gr, #2 Stoeger X-Match 8.18gr

I ordered some QYS 8.18gr 😂

This is from my CMP M853
i use RWS R-10 straight from the tin , i used to sort weight , head size , to much time not enough results .
 
Today i i confirmed one of my scopes went nuts ! three times i reset to optical zero and three times i ended up with no bottom and no right adjustment but crosshairs right on target BULLSEYE ! this was on two different guns , the scope is only a UGT bug buster so not much loss and i sent in a request for a repair . then i shot my little Diana 23 , very hard to cock this springer , had to use both my third and little fingers to get the job done .
 
I shot my RAW HM1000x LRT .22 at 50 and 75 yards with JSB deep base and JTS shallow base 25s to see which was best. The wind was up and down and they were about the same. When I get a calm day I'll give it another go. I then shot my B.S.A. R10 SE laminate TH .22 with JTS 18s at 885 f.p.s. at 50 and 75. The wind had died and the Beezer out shot the RAW. I have it topped with an Athlon Heras SPR 4-20 and the RAW has an Athlon Ares ETR UHD 4.5-30. I did not go to 100 because the wind blew it down the other night.
